CARPET OR UPHOLSTERING FABRIC.

SPECIFICATION forming part of Letters Patent No. 420,269, dated January 28, 1890.

Application filed June 7, 1889- Serial No, 313 A57. (Speeimena) To all whom it may concern:

Be it known that I, GOLDSBOROUGH S. GRIFFITH, J r., a citizen of the United States, residing in the city of Baltimore and State of Maryland, have invented a certain new and useful Improvement in Carpets or Upholstery Fabrics, of which the following is a full, clear, and exact description.

This invention relates to carpet fabrics, or fabrics for furniture-covering, of the character having a back of inferior material and a faceof superior material; and the object of the invention is to produce a solid-back carpet or other fabric having good wearing properties and a smooth face, either adapted to receive designs by printing or having the design produced therein by colored yarns.

The invention consists of a carpet or other fabric having a back formed of longitudinal stuffing-threads, pairs of binder warp-threads, and weft-threads, and a face of weft-threads united to the weft of the back by binderthreads,which alternately interlock with back weftthreads, as I will proceed now more particularly to set forth .and claim.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure 1 is a diagrammatic plan view of my fabric; Fig. 2, a longitudinal section, and Fig. 3 a transverse section.

The back has a stuffing composed of groups of four (more or less) strands or threads a, of jute or equivalent heavy and strong material, arranged parallel to the warp and laid parallel to one another, and extended from beam to beam, either independently of the harnesses or through harnesses of their own in the loom. Between the successive groups is a pair of binder warp-threads b, of cotton or other material, which threads are to be operated, as usual, by the usual harnesses of the loom; and co-operating with the binder warpthreads and on opposite sides of the stufling are the weft-threads c, of cotton or linen. In order to make straight and strong selvages, there is the outside pair of binder warpthreads I), of cotton or other material, and the straight longitudinal thread cl, bound in by the weft c. The back thus constructed is hard, solid, and inelastic in all directions.

The face is composed, by preference, of

woolen weft-threads 6, shot in single or in pairs, to make a smooth surface, and bound in by worsted warp-threads f, arranged in pairs and harness-operated, and these weftthreads 6 are laid flat across the back, without loops, and beaten up closely. The warps f are alternately engaged with the cotton wefts, and are crossed between each two pairs of woolen wefts.

It will be observed that the woolen weft running at right angles to the stuffing cannot sink into it or between its constituent members, and hence a very hard and solid carpet is produced, which will not permit dust to sift through. The face, being hard, fiat, and smooth, will not sprout, as does tapestry or body-brussels-that is, the faceyarns will not catch and pull out and will not catch and hold dirt. It may be swept easily, and is susceptible of being easily and veryperfectly printed. Made up in solid colors my carpet is particularly well adapted for halls and for filling under and around rugs.

The selvage being straight, lengths of my carpet may be sewed together with abutting edges, as in the case of tapestry, brussels, and the like. The'selvage preferably contains also the two stuffing-threads a, arranged one above the other.

What I claim is 1. An improvement in carpet fabrics or other fabrics, consisting of a back composed of groups of four (more or less) stuffingthreads laid staight and parallel and running lengthwise of the warp, binder warpthreads on each side of the groups of stuffingthreads, and weft-threads interlocked with the warp-threads and binding in the groups of stuffing-threads, and a fiat face composed of weft-threads crossing the stuffing-threads at right angles, and binder warp -threads interlocked with the weft-threads of the back and with the face weft-threads, substantially as described.

2. A carpet fabric or other fabric having a back of straight parallel stuffing-threads, binder warp-threads, and weft'threads, a face of straight flat weft-threads and binder warpthreads interlocked with the weft of the back, and selvages having part of the back binderwarps and a straight thread arranged outside linen binder warps alternating with the groups of stuffing-threads, and a cotton or linen weft, and a face composed of woolen IO weft-threads arranged in pairs crosswise of the back and fiat theron, and binder-warps of worsted threads woven with the woolen face-weft and with the cotton or linen backweft, substantially as described.

In testimony whereof I have hereunto set 15 my hand this 6th day of June, A. D. 1889.
